17.7.10 Fault Signalization
The system is protected against failure states, by stopping and braking the drive system, and respective signalization. The fault
indicator ashing briey and the accumulator indicator shows the fault state. Some defects are cleared automatically (e.g.: drive
overheating). When drive or electronics is overheated, an short acoustic signal occurs before the drive is blocked.
